Edward Augustus (Gus or Gussie) Bowles, VMH (14 May 1865 – 7 May 1954), known professionally as E. A. Bowles, was a British horticulturalist, plantsman and garden writer. He developed an important garden at Myddelton House, his lifelong home at Bulls Cross in Enfield, Middlesex and his name has been preserved in many varieties of plant.
E. A. Bowles was born at his family's home, Myddelton House (1818), near Enfield. He was of Huguenot descent through his maternal great-grandmother and his father, Henry Carington Bowles Bowles (sic) (1830–1918), son of Anne Sarah Bowles, who inherited Myddelton House and married Edward Treacher. Their son adopted his mother's surname in 1852 for inheritance purposes and married E.A. Bowles' mother, Cornelia Kingdom (1831–1911), in 1856, was Chairman of the New River Company, which until 1904 controlled the artificial waterway that flowed past Myddelton, bringing water to London from the River Lea. Through his elder brother Henry, who after 1894 lived at neighbouring Forty Hall, Bowles was the great uncle of Andrew Parker Bowles (born 1939), whose first wife, Camilla Shand, became Duchess of Cornwall on her marriage to Charles, Prince of Wales in 2005.
Described as "too delicate for public school", Bowles spent much of his childhood at Myddelton before reading divinity at Jesus College, Cambridge. He had wanted to enter the church, but family circumstances, including the death of a brother and sister from tuberculosis in a three-month period of 1887, militated against this; so he remained at Myddelton and, in the words of one historian, "devoted himself to social work, painting, and natural history, particularly entomology".
